Area of Science:

  • Orthotics and Biomechanics
  • Hand Therapy and Rehabilitation
  • Rheumatology and Arthritis Management

Background:

  • Limited evidence exists on patient satisfaction and occupational performance with CMC orthoses.
  • Understanding the impact of orthotics on thumb CMC joint arthritis is crucial for treatment efficacy.
  • Patient preference and satisfaction are key factors in adherence to orthotic devices.

Purpose of the Study:

  • To evaluate patient satisfaction with the CMC Controller Plus orthosis.
  • To assess patient preference for the CMC Controller Plus orthosis.
  • To determine the effect of the CMC Controller Plus orthosis on pain and function in CMC joint arthritis.

Main Methods:

  • A cohort study was conducted at two outpatient hand therapy clinics in Pennsylvania and Florida in 2019.
  • Participants diagnosed with thumb CMC joint arthritis received the CMC Controller Plus orthosis at no cost.
  • The study focused solely on the CMC Controller Plus orthosis intervention, without concurrent hand therapy.

Main Results:

  • The CMC Controller Plus orthosis demonstrated a large effect size (1.29) in improving patients' functional status.
  • A moderate effect size (0.49) was observed for pain reduction in patients using the orthosis.
  • Functional status improved by 52% and pain reduced by 29% in patients using the CMC Controller Plus.

Conclusions:

  • The CMC Controller Plus orthosis significantly enhances functional status for individuals with thumb CMC joint arthritis.
  • The orthosis effectively reduces pain associated with thumb CMC joint arthritis.
  • The observed improvements in function and pain were both statistically and clinically significant.
